Mine cost me nothing.
Even the life time tank of propane,,, hose,,, and 2 flame tips cost nill...
Our fad shop had the 750 paint in stock...
I fabbed up a up-right stand,,, added Four 5/8 deep sockets back to back like a cross and welded them to a Tumbler handle...
Its fairly tall so I can have my cake pan on an angle with a towel to catch the brass on the rotation...
I practic my timing with the paint,,, then the same in a dark room,,, no paint since I flip the brass just as it gets to a very thin glow...
The torches are pretty hot,,, 4 1/2 ish seconds per turn... 400 brass @ 35 minutes...
Fast frugal and simple.
